This document summarizes a student practice at JINR, Dubna in 2011. The practice involved 3 students from Czech Technical University in Prague and 1 student from University of Bucharest who aimed to understand photon production and its role in collective phenomena explanations. They sought to simulate photon spectra from high energy collisions and the energy deposition of photons in an electromagnetic calorimeter using GEANT, PYTHIA and PAW software. The calorimeter simulation showed it could detect low energy photons with small background contribution from high energy particles due to its VETO detector and ability to locate photons within 2 cm.
